2. The level of dissolved oxygen in the surface water of a lake is vital to maintaining the lake's ecosystem. Environmentalists from the University of Wisconsin monitored the dissolved oxygen levels over time for a sample of 25 lakes in the state (Aquatic Biology, May 2010). To ensure a representative sample, the environmentalists focused on several lake characteristics, including dissolved organic compound (DOC). The DOC data (measured in grams per cubic-meters) for the 25 lakes are listed in the accompanying table. The population of Wisconsin lakes has a mean DOC value of 15 grams/m3. Use a hypothesis test (at a = .10) to make an inference about whether the sample is representative of all Wisconsin lakes for the characteristic, dissolved organic compound.
